ROTARY-DISK RASP.

SPECIFICATION forming part of Letters Patent Na 641,543, dated January 16, 1900.

Application filed October 10, 1 8 9 9.

T0 at whom it nut/y concern:

Be it known that-I, JOHN LEE POPE, a citizen of the United States, residing at Croft, in the county of Mecklenburg and State of North Carolina, have invented a new and useful Rotary-Disk Rasp, of which the following is a specification.

This invention relates to rotary-disk rasps for use in farriery, and has for its object to provide a simple implement in disk form combining the features of a rasp and file and designed for use in trimming a horses hoof for the reception of a shoe and to pare the wall and sole at the same time and leave the sole somewhat lower than theIwall where the shoe rests and prevent contact of the shoe with the sole; furthermore, to have a device also adapted for use in filing nails and preparing clenches after the shoe has been driven.

Other objects and advantages will appear in the subjoined description and the novelty hereinafter claimed, the preferred embodiment of the invention being illustrated in the accompanying drawings, wherein Figure 1 is a perspective View of an imple- 'ment embodying the features of the invention. Fig. 2 is a transverse vertical sectional view of the same.

Similar numerals of reference are employed to indicate corresponding parts in the views.

The numeral 1 designates a spindle of suitable length and diameter and near one end having thereon an enlargement 2 to provide opposite shoulders 3 and 4. From the shoulder 4: to the terminal of the spindle an angular head 5 is formed, on which is fitted a disk 6. Against the shoulder 3 a handle or grip 7 has loose bearing, and a bore is longitudinally formed in the said handle or grip of such dimension as to permit the spindle 1 to have unretarded rotation. The handle or grip 7 is of less length than the distance between the shoulder 3 and the extremity of the spindle 1 opposite that 011 which the angular head 5 is formed, and over the said projecting portion of the spindle a power-transmitting cap 8 is fastened by a set-screw 9, extending through a part of the said cap and impinging against the spindle. The closed end 11 of the cap 8 has an opening 10 formed therein to receive a flexible shaft or cable 12, which is held in firm connection with the said serial no. 733,180; (No model.)

cap 8 by a set-screw 13. It is intended that the flexible shaft or cable 12 be driven by any suitable mechanism, and the rotation of the same causes a rotation of the spindle 1 through the medium of the cap 8.

The periphery of the disk 6 is beveled equally on opposite sides, as at 14, to a cutting edge 15, and by this means opposite inclined faces are formed, in which file-teeth 16 are cut in diagonal lines and terminating at an inner circular margin 17. From the margin 17 inwardly on both sides of the disk 6 rasp-teeth 1b are cut, and adapted to be arranged in any preferred manner and in ac cordance with the most approved pattern or disposition to'give the best result. The teeth 16 and 18 on opposite sides of the disk may vary as to gage as well as specific kind, and thereby embody in the implement both a rub hing-up and a finishing surface. As more clearly shown in Fig. 2, the portions of the opposite faces of the disk adjacent the center are slightly curved or raised for obvious reasons.

In operation motion is imparted from the flexible shaft or cable 12 to the spindle 1 while the implement is held by the grip 7. Rotary motion is thus given the disk 6, and by bringing the opposite faces of the latter against the various parts of the hoof, which will beregulated by the kind of work to be done, the hoof can be primarily prepared (to receive a shoe or dressed after the shoe is driven. The cutting edge 15 is particularly useful in preparing clenches and in filing nails, and the implement can be held at any angle desired without interfering with its rotary movement, and thus accomplish work usually requiring considerable time in a much more expeditious and convenient manner. The beveled file edges can also be used alone for various purposes, as may be found necessary, and likewise portions of the rasp-faces.

It is intended that the implementbe made in differentsizes, and'variations in the form, proportion, and minor details of construction might be made to suit various applications without departing from the spirit or sacrificing any of the advantages of the invention.
